PETROLEUM GAS-BURNER FOR H EATING PURPOSES.

@Llp Stimuli referat tu iu time` yrttn's atmtrut making ont nt tigesame.

Bo it known that I, D. L. HOLDEN, ofthe city of New Orleans, parish ofOrleans, and State of Louisiana, hnverinvented u. certain newA anduseful improvement inV Petroleum Gas-Burners; and I do hereby declarethe followingto be a full, clcar, and exact description otthe same,reference being had to the annexed drawings, making a part of thisspecification, in which` *l Figure 1 is' a perspective view of a burnerthat contains uiy improvement; and

-Figure 2, a sectional view of the same.

My invention consists of n' concentric chamber to contain' the oilaroundpan interior or central air-cheminer.

or iluo, und the o lect accomplished by it' is a more rapid generationoff gas, and a consequent intenser heat than obtains ,in the burncrsofGray, Seroni, Dopp, Jcrvey, and all others with which I have anyacquaintance.

Rcfcrringto the drawings,.A-represents a burner, Bv the centralair-chamber, and C the concentric oilchamher that l have devised. l

In thc operation of my burner the oil enters the concentric chamberthrough the pipe D, which,` it willbe understood, is provided ivithvalves and mechanical appliances' to prevent leakage, and completelysurrounds thc central air-chamber B. Heat being applied in any usualmanner, (and, from the construction of my burner, g

it will be seen that this can be donc in so general Vand difuso a mannerthat the heat will be'hrcught' to bear upon the oil on all" sides) gasor vapor is quickly generated, and, issuing from thc oil within theconcentric chamber C, enters the central air-chamber, near the toptl1ereof,'through thc apertures or vent-holes D.` Now,

as soon as the evolution 'of gas begins it can be lighted by theapplication of a-ilnmc t'o the rents D. Issuing p vfrom thcsevents, theburning gas nnpinges upon the vwalls of 'the air-el1amber, and `quicklysnperincluces therein avery great degree of heat. The walls being thusheated, the evolution offgas becomes more rapid, and this induces a morerapid combustion. The. result is, to produce and to' keep .up a veryintense degree of heat, which is the "object sought after. It' a stillgreater heat be desirabie, it can be produced by the application of'ashort metallic chimney fitted over the burner, und resting upon the anchE, which, it will bc observed, encircles the burner; or, it` adistribution of the heator liamc labove the burner `be required, aperforated |met-allie cap mav be applied with the certaintyof attaininga generaldiiusion of the said ame. v

In manufacturing my burner I either cast itas aneutirety, Yor the twochambers B and, C may De establishedhy the insertion 'of the section cfapipe on the plan shown upon the drawings. I do not limit myself to anyparticular or specified mode of making my invention, that is to say,'ofmanufacturing it.

. Having thus described my invention, what I claim, and desire to secureby Letters Pat-ent, is

A gas retort and burner, consisting of the concentric or annularoil-chamber C, in. combination with a central lair-chamber or tine, B,provided' with 'perforations D at or near the top of chamber C,substantially as and for the purpose described. I
